I remember in grade school that we were taught that red, yellow and blue were the primary colors. The one that was taught in school was the RYB model. It's actually a historical color model used in art and painting, even today. I admit, this was very easy to learn.
What high school taught us however, was that there was more than one kind of primary color combination: additive and subtractive.
Subtractive primary colors are used to produce the needed colors on reflected light. In the modern printing industry, however, you won't find RYB. The modern printing standards use a different set, called CMY. Meaning Cyan, Yellow And Magenta. They added black (referred to as the key. The brightness, or key of a print is determined by the amount of black ink used.) as well so they don't have to combine the colored inks to reproduce the black color.
The other commonly used model is the RGB color model. Unlike the CMYK model which is subtractive, this is additive. Means the Red, Green and Blue are combined in different intensities to produce the other colors. This is commonly used for emitted light like PC LCD/LED monitors and digital photography.
That's about the basics of it. If you're interested in checking out more about primary colors, please see this wikipedia page on Primary Colors.
